As shown in Supplementary Figure S2, two out of more than 30 anti-tumor chemical agents screened, the pharmacological agents of epigenetic drivers BRD4 (JQ1) and histone deacetylase (HDAC, LBH589) (Filippakopoulos et al., 2010), and the pro-survival Akt (MK-2206) and Bcl-2 (ABT-737), exhibited strong cooperative effects with VS-6063 in terms of cell viability inhibition. This evidence concerns the gene HDAC9 and neoplasm.
